Braneworld Kaluza-Klein Corrections in a Nutshell
Sugumi Kanno, Jiro Soda
Evaluating Kaluza-Klein (KK) corrections is indispensable to test the braneworld scenario. In this paper, we propose a novel symmetry approach to a 4-dimensional effective action w…
Asymptotic Form of Gopakumar-Vafa Invariants from Instanton Counting
Yukiko Konishi, Kazuhiro Sakai
We study the asymptotic form of the Gopakumar-Vafa invariants at all genera for Calabi-Yau toric threefolds which have the structure of fibration of the A_n singularity over P^1. W…
Boson Sea versus Dirac Sea -- General formulation of boson sea through supersymmetry --
Yoshinobu Habara, Holger B. Nielsen, Masao Ninomiya
We consider the long standing problem in field theories of bosons that the boson vacuum does not consist of a `sea', unlike the fermion vacuum. We show with the help of supersymmet…
A mechanism of the large-scale damping in the CMB anisotropy
Masafumi Fukuma, Yuji Kono, Akitsugu Miwa
We present a mechanism through which a certain class of short-distance cutoff affects the CMB anisotropies at large angular scales. Our analysis is performed in two steps. The firs…
Supersymmetric large-N reduced model with multiple matter
Hikaru Kawai, Tsunehide Kuroki, Takeshi Morita
We showed in hep-th/0303210 that the Dijkgraaf-Vafa theory can be regarded as large-N reduction in the case of supersymmetric U(N) gauge theories, with single adjoi…
Bulk inflaton shadows of vacuum gravity
Tsutomu Kobayashi, Takahiro Tanaka
We introduce a -dimensional vacuum description of five-dimensional bulk inflaton models with exponential potentials that makes analysis of cosmological perturbations simple…
Properties of Kaluza-Klein black holes
Hideaki Kudoh, Toby Wiseman
We detail numerical methods to compute the geometry of static vacuum black holes in 6 dimensional gravity compactified on a circle. We calculate properties of these Kaluza-Klein bl…
Deconfining Phase Transition as a Matrix Model of Renormalized Polyakov Loops
Adrian Dumitru, Yoshitaka Hatta, Jonathan Lenaghan +2
We discuss how to extract renormalized from bare Polyakov loops in SU(N) lattice gauge theories at nonzero temperature in four spacetime dimensions. Single loops in an irreducible…
Dimensional Hierarchy in Quantum Hall Effects on Fuzzy Spheres
Kazuki Hasebe, Yusuke Kimura
We construct higher dimensional quantum Hall systems based on fuzzy spheres. It is shown that fuzzy spheres are realized as spheres in colored monopole backgrounds. The space nonco…
Superfield formulation of central charge anomalies in two-dimensional supersymmetric theories with solitons
K. Shizuya
A superfield formulation is presented of the central charge anomaly in quantum corrections to solitons in two-dimensional theories with N=1 supersymmetry. Extensive use is made of…
Negative Energy in String Theory and Cosmic Censorship Violation
Thomas Hertog, Gary T. Horowitz, Kengo Maeda
We find asymptotically anti de Sitter solutions in N=8 supergravity which have negative total energy. This is possible since the boundary conditions required for the positive energ…
Closed String Field Theory with Dynamical D-brane
Tsuguhiko Asakawa, Shinpei Kobayashi, So Matsuura
We consider a closed string field theory with an arbitrary matter current as a source of the closed string field. We find that the source must satisfy a constraint equation as a co…
Eigenvalues of Ruijsenaars-Schneider models associated with root system in Bethe ansatz formalism
Boyu Hou, Ryu Sasaki, Wen-Li Yang
Ruijsenaars-Schneider models associated with root system with a discrete coupling constant are studied. The eigenvalues of the Hamiltonian are givein in terms of the Beth…
Quantum & Classical Eigenfunctions in Calogero & Sutherland Systems
I. Loris, R. Sasaki
An interesting observation was reported by Corrigan-Sasaki that all the frequencies of small oscillations around equilibrium are " quantised" for Calogero and Sutherland (C-S) syst…
Non-unitary evolutions of noncommutative worlds with symmetry
Naoki Sasakura
Motivated by describing time-evolutions of noncommutative worlds, I discuss symmetry-preserving evolutions of noncommutative worlds of finite dimensional representation spaces. An…
Towards Noncommutative Integrable Equations
Masashi Hamanaka, Kouichi Toda
We study the extension of integrable equations which possess the Lax representations to noncommutative spaces. We construct various noncommutative Lax equations by the Lax-pair gen…
Dilaton Stabilization in (A)dS Spacetime with Compactified Dimensions
Kunihito Uzawa
We investigate dilaton stabilization in a higher-dimensional theory. The background geometry is based on an eleven-dimensional Kaluza-Klein/supergravity model, which is assumed to…
Torus Knot and Minimal Model
Kazuhiro Hikami, Anatol N. Kirillov
We reveal an intimate connection between the quantum knot invariant for torus knot T(s,t) and the character of the minimal model M(s,t), where s and t are relatively prime integers…
Dilaton Dynamics in (A)dS_5 x S^5
Kunihito Uzawa, Kei-ichi Maeda
We investigate a stabilization of extra dimensions in a ten-dimensional Kaluza-Klein theory and IIB supergravity. We assume (A)dS_5 x S^5 compactifcation, and calculate quantum eff…
Exact solution of Belavin model with open boundary condition
W. -L. Yang, R. Sasaki
Belavin model with open boundary condition is studied. The double-row transfer matrices of the model are diagonalized by algebraic Bethe ansatz method in terms of the intertw…
Localization of heterotic anomalies on various hyper surfaces of T^6/Z_4
Stefan Groot Nibbelink, Mark Hillenbach, Tatsuo Kobayashi +1
We investigate the structure of local anomalies of heterotic E_8 x E_8' theory on T^6/Z_4. We show that the untwisted states lead to anomalies in ten, six and four dimensions. At e…

Radionic Non-uniform Black Strings
Takashi Tamaki, Sugumi Kanno, Jiro Soda
Non-uniform black strings in the two-brane system are investigated using the effective action approach. It is shown that the radion acts as a non-trivial hair of the black strings.…
